答案以及解析
1.答案：C
解析：考察时态语态。最近，由于 COVID-19 的流行，生活成本一直在稳步攀升，导致一些人退出了大城市 的竞争。由时间状语 for many years 以及逗号后分句的时态可知此处表示过去发生并且仍在进行的动作，故用 现在完成进行时，故选 C。
2.答案：B
解析：confusing令人因惑的；confused.感到因惑的；第一个空confused修饰expression，表示自身的感受；第二个空用过去完成时，表示not understand的动作发生在showed之前；句意：她脸上因惑的表情说明她还没有完全明白经理的意思。根据句意，故选B。
3.答案：A
解析：本题主要考查过去将来时。根据句意，“我们”的空调卖得很好，但是几十年前没有人能想到会有这么大的市场份额。decades of years ago 表明时间是过去，could have imagined 表示对过去事实的推测，imagine 意为“想象”，表明在当时属于将来的事情，因此用过去将来时。主语 they 为复数，因此使用 were to have。故正确答案为A。
4.答案：D
解析：我在英国工作的时候学过钢琴，考查一般过去时表达动作开始在过去结束在过去的用法，故选D。
5.答案：B
解析：句意：上个月我就这种劣质服务向这家宾馆的经理投诉，但直到现在我还没收到他的回复。根据时间状语up to now可知，此处用现在完成时。
6.答案：C
解析：考查时态。句意：警察的注意力突然被放在部长汽车下面的一个小盒子吸引住了。定语从句中“放在部长汽车下面的一个小盒子发生在注意力被吸引”之前，即过去的过去，应用过去完成时。故选C。
7.答案：A
解析：本题主要考查现在进行时、动词词组和句子分析。本题中 you referred to 是 the foreign friends 的定语，所以本句缺少谓语动词，第一空应填 are，表示“外国朋友正期待着”，排除B、C项，又由于 look forward to 后加动名词，只有A项符合。故正确答案为A。
8.答案：B
解析：考查时态和主谓一致。句意：在过去的几年中，深圳发生了巨大的变化。由“in the past few years"可知，句子时态用现在完成时，take place意为 “发生”，无被动语态，主语changes是复数。故选B。
9.答案：A

11.答案：B
解析：考查固定短语、时态和主谓一致。句意：一位歌手兼舞蹈家出席了晚会。根据句意可知，句中涉及固定短语“be present at…”，意为“出席……”，故可排除C和D，句子陈述的是过去发生的事，应用一般过去时，动词要用过去式，句中“A singer and dancer”指一个人，有歌手和舞蹈家的双重身份，故“be”应用“was”。故选B项。
12.答案：B
解析：根据句意和时间ever since可知这里表示从那时到现在一直保持的状态，用现在完成时。主语是The number of谓语用三单。故选：B。
13.答案：C
解析：分析句子，since表示"自从"，引导时间状语从句，从句应用一般过去时，主句应用现在完成时，且construct与主语The building之间是被动关系，所以第一空应用现在完成时的被动语态，即has been constructed。C选项符合本句时态和语态。故选：C。
14.答案：D
解析：考查时态。根据语意，如果你努力学习，你将来会有更多的选择。主句用一般将来时，从句用一般现在时表将来，遵循主将从现的原则。故选：D。
15.答案：D
解析：根据题意，一你看上去很累。你怎么了？一今天的运气很差！在我到达机场的时候，飞机已经起飞了。本题考查动词的时态。分析句子结构可知，arrived的动作发生在过去，leave这个动作发生在arrived之前，即过去的过去，过去完成时态。故选：D。
